Introduction to Flutter Workshop

It's time to call our web service using HTTP(s). Flutter includes an HTTP and JSON parser, the only thing we need is to add the dependency in pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  http:

Now we are ready to use HTTP services. Warning for Android development: you have to add INTERNET permission to the Android app to make it work. For that you need to find AndroidManifest.xml in the android/app/src/main folder and add as a new children of the root element

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.coffee_masters">
    <uses-permission android:name="android.permission.INTERNET" />
<!-- ... -->

Web and iOS targets have access to Internet without any explicit permission request.
